  • LED driving device and driving system thereof
    Patent number: 8450949
    Abstract: A light emitting diode (LED) driving device outputs a driving signal according to a select signal, an update data, and an update command. The driving device includes a buffer circuit, a display data storage, and a signal generating circuit. The buffer circuit includes register series and a bypass register. The buffer circuit selectively stores the update data in the register series and the bypass register according to the update command. The display data storage stores multiple display data. The display data storage updates the display data by using the update data stored in the register series according to the update command. The signal generating circuit outputs the driving signal according to the display data. When the update data is stored in the bypass register, the clock of the update data passing through the driver is reduced.
